CinemaCon gets underway this Monday, but Steve is already in Las Vegas snapping pictures of all the cool promo posters, banners, and standees he can find.  For those unaware, CinemaCon is a convention put on for all the major theater owners in order to get a look at what the studios have to offer for the rest of the year; it’s basically Comic-Con for theater owners.  While walking the floor, Steve found a new promo poster for director Carl Rinsch's 47 Ronin.  The pic stars Keanu Reeves and it's about a troupe of banished samurai long to restore their honor and find vengeance against the treacherous Lord Kira (played by Tadanobu Asano) who was responsible for the death of their master.  We got a look at a different promo poster at the 2011 Licensing International Expo, but this one has 100% more fire and plays up the 3D aspect of the action film.Hit the jump to check out the promo poster, and be sure to check back over the next few days for all our coverage from CinemaCon 2012.  47 Ronin opens on November 11th in 3D.UPDATE: Found a better version of the 47 Ronin poster.  It's been added after the jump.For more new posters from CinemaCon, here’s a few links:

Here’s the synopsis for 47 Ronin:

The troupe of banished samurai long to restore their honor and find vengeance against the treacherous Lord Kira (played by Asano, who is in theaters now as Hogun in Thor) who was responsible for the death of their master. Kai is the uneasy compatriot in their company and his standing will be questioned even more as he falls in love with Mika (Shibasaki), daughter of the fallen master. The film presents a quest where the ronin (the term for samurai with no master) face trials that test their mettle and their loyalty to one another.
